The present invention provides for a unit dose packaging for a solid pharmaceutical dosage form to be taken in a dosage regimen continuously for more than one weekly interval. The packaging comprises a series of blister packs, each of the blister packs containing the solid pharmaceutical dosage form for one weekly interval. The solid dosage form is arranged in individual pockets on the blister pack to present and identify each dosage separately and to form a patterned sequence of dosages to allow for ease of compliance with the dosage regimen whereby non-compliance is immediately visually identifiable by reviewing the dosages remaining on the blister pack.

Why it's free to use
- Filed April 2, 1992 and granted September 19, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 2, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 2, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
